I have a 2001 Buick LeSabre Custom with a 3.8. The passenger side window, mirror and lock does not work from either door control or the key fob. All other windows and locks work fine along with the drivers side mirror. Does anyone have any suggestions or experienced the same problem.

Thanks.

Well, basically, all three of those things are controlled by the driver'* door module.......

A scan tool, Like a Tech II, makes diagnosis simple, but they don't grow on trees.....

About all you can do, is get wiring diagrams for the mirror, lock , and window on the front driver'* side, to diagnose if the proper signal is getting to the Driver'* Door Module, and if it has power and ground to it......if that all checks out, then you need a DD Module....
